99 intake manifold...
I was reading about the newer manifolds about getting more HP. It was saying that production started Mid 99' to 2001.
My question is, did the manifolds in all 99' change, or only the ones build later on in 99'.
Better yet, how Can I tell the difference?

i believe its only mid 1999 to 2001. and the intake runners are diiferent. it ballons under the throttle body. ill post a pic of the one off my 1998 and the one off the 99' 4.0 i got to put in.

the late 99/2000 intakes flow alot more CFM's than the older style did also they have equal length runners. I've done this swap to mine and it does make a difference but not really noticeable unless you have a highflow TB and CAI.
